Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ventilation mechanism in a roof window device of a vehicle such as a passenger car.

(Prior Art) There are two types of vehicle roof window devices called sunroofs: one in which a cover body for opening and closing the roof window opening is tilted down from the window opening closing position and then moved backward; In addition to the movement, there is a model that tilts the cover body up from the window opening closed position, and each model has a ventilation hole formed below the window opening, which can be opened and closed with the lid member. ing. The vehicle is configured to be substantially ventilated by opening both the cover body and the lid member.

It is of course necessary that the vent cover member can be manually opened and closed, but when opening the cover body, the cover member must also be opened, so the opening operation of the cover member is linked to the opening operation of the cover body. It is preferable.

As a conventional technique of this kind, as shown in Japanese Utility Model Application Publication No. 182829/1983, there is a technique in which a lid member is moved together with the backward movement of a cover body.

(Problem to be solved by the invention) Moving the cover body and the lid member together is
By providing the cover body with a member that engages with the lid member, the structure can be easily configured.

However, with the above-mentioned model that involves tilting the cover body, it is necessary to ventilate with the cover body in the tilting position, and when the cover body is tilting up, the cover body and lid must be Because the movement directions of the members are different, it is difficult to open the lid member simply by providing an engagement member on the cover body, and even if a drive cable is used, it is difficult to open the lid member when moving the cover body backward. It is difficult to use the vent cover member because it is opposite to the moving direction of the drive cable, and therefore, in the past, it has not been practiced to open the vent cover member when the cover body is tilted up.

The present invention utilizes the free end side of the drive cable for tilting the cover body, that is, the other end side that moves in the opposite direction to the one end side of the drive cable that is interlocked and connected with the cover body. It is an object of the present invention to provide a ventilation mechanism in a roof window device for a vehicle, which can solve the various problems mentioned above by configuring the vent cover member to open.

(Means for Solving the Problem) A specific configuration for solving the problem in the present invention is to form a window opening on the roof of the vehicle that is opened and closed by a cover body, and to provide a pair of window openings on the left and right sides of the window opening. A guide rail is arranged, and a slide member is provided on the guide rail to be slid in the front-rear direction by one end side of a drive cable, both ends of which are oriented in the same front-rear direction, and a slide member is provided between the slide member and the cover body. The forward movement of the slide member causes the cover body to tilt up from the window opening closed position, centering on the front part, and the backward movement of the slide member causes the cover body to tilt down from the window opening closed position. In a roof window device for a vehicle, a roof window device for a vehicle is provided with a tilt mechanism for moving rearward along with the window opening, a ventilation hole is formed below the window opening, and the ventilation hole is equipped with a lid member that can be opened and closed manually. Interlocking means is provided between the cover member and the other end to open the cover member by movement of the drive cable in the tilting direction of the cover body.

(Function) When the drive device 25 is actuated to move the drive cable 28 from the state where the cover body 5 closes the window opening 2, the slide member connected to one end of the drive cable 28 moves forward. Then, the cover body 5 is tilted up centered on the front part via the tilt mechanism 13.

Since both ends of the drive cable 28 are oriented in the same front and rear direction, when one end connected to the slide member moves forward, the other end moves backward, and this other end moves the lid member backward through the interlocking means. to open the ventilation port 31.
